Specifically, benthic organism B to be identified has m similar species, namely A 1 ,A 2 ,...A m . If there is a proximity N (A) k ,B)=max{N(A i B), i is 1.ltoreq.m, then B and A are considered k Nearest to it, it can be determined that B belongs to A k Types.
Let A, B be similar species on the discourse domain U, then the closeness of the two is:
N(A,B)=1/2[A·B+(1-A⊙B)]
This closeness is also called lattice closeness, where a·b=max { a (x) ζb (x) } is the inner product of similar species a and B; A.sub.B=min { A (x) and B (x) } are the outer products of the similar species A and B.

And if similar species are not identified in the preliminary identification result, responding to the morphological characteristic information of the benthonic organisms to identify the species of the benthonic organisms and the characteristic information of the benthonic organisms, and supplementing the species of the benthonic organisms and the characteristic information of the benthonic organisms into a characteristic database when the benthonic organisms are identified as new species, so as to gradually perfect the characteristic database.
According to the embodiment of the disclosure, the optical images of the benthonic organisms are acquired, classified, sorted and sorted, classified under the corresponding directory, subjected to color reconstruction, and obtained. Further, feature extraction is carried out on the reconstructed optical image of the benthonic organism to obtain morphological feature information of the benthonic organism, and each species in a feature database is initially identified according to the appearance feature information of the benthonic organism to obtain an initial identification result. And if at least one similar species is identified in the preliminary identification result, respectively calculating the closeness of morphological characteristic information of the benthos and characteristic information of each similar species, and determining the species with the highest closeness in the at least one similar species as the benthos species. Because each species in the characteristic database is initially identified according to the appearance characteristic information of the benthonic organism, the identification difficulty can be reduced, the subsequent calculation is reduced, when at least one similar species is identified, the closeness of the morphological characteristic information of the benthonic organism and the characteristic information of each similar species is respectively calculated, and the species with the largest closeness in the at least one similar species is determined as the species of the benthonic organism, so that the identification efficiency and the identification accuracy are improved, and the benthonic organism identification method based on the morphological characteristic information of the benthonic organism is applicable to various biological identification and has strong universal adaptability.
